Abstract A distribution function ( F on [0,∞) belongs to the subexponential class if and only if 1− F (2) ( x ) ~ 2(1− F(x) ), as x → ∞. For an important class of distribution functions, a simple, necessary and sufficient condition for membership of is given. A comparison theorem for membership of and also some closure properties of are obtained. 1980 Mathematics subject classification (Amer. Math. Soe.) : primary 60 E 05; secondary 60 J 80.
